Where in Winnipeg can i get fixie parts for my old roadie I never ride? It's shima-no atm, i wana go fixed for little $$$ Can I just remove the casette and replace with a single? Where can I get that, and I assume I'll need spacers ect.

You can get a rear wheel with a flip-flop hub from Norco for $105. This should be available from any bike shop in Winnipeg. You then need a fixeg cog and a lock ring, these vary in price. NRG and Marinoni are both good distibutors that sell fixed gear stuff. I would say go to a LBS that you like and tell them what you want, if they don't know where to get it, just give them the distributor names I mentioned.

Sweet, can i not use my current hub/wheel? A fixed cog that screws on like the current cassette. Pull all shifters and shorten up the chain then ride in style. Paris, that's from a Hip tune.....what city? I forget.
